The images were hand-segmented to create a classification for every pixel. Each instance is a 3x3 region.\n \n### Attribute Information  \n\n1.  region-centroid-col:  the column of the center pixel of the region.\n2.  region-centroid-row:  the row of the center pixel of the region.\n3.  region-pixel-count:  the number of pixels in a region = 9.\n4.  short-line-density-5:  the results of a line extractoin algorithm that \n          counts how many lines of length 5 (any orientation) with\n          low contrast, less than or equal to 5, go through the region.\n5.  short-line-density-2:  same as short-line-density-5 but counts lines\n          of high contrast, greater than 5.\n6.  vedge-mean:  measure the contrast of horizontally\n          adjacent pixels in the region.  There are 6, the mean and \n          standard deviation are given.  This attribute is used as\n         a vertical edge detector.\n7.  vegde-sd:  (see 6)\n8.  hedge-mean:  measures the contrast of vertically adjacent\n           pixels. Used for horizontal line detection. \n9.  hedge-sd: (see 8).\n10. intensity-mean:  the average over the region of (R + G + B)/3\n11. rawred-mean: the average over the region of the R value.\n12. rawblue-mean: the average over the region of the B value.\n13. rawgreen-mean: the average over the region of the G value.\n14. exred-mean: measure the excess red:  (2R - (G + B))\n15. exblue-mean: measure the excess blue:  (2B - (G + R))\n16. exgreen-mean: measure the excess green:  (2G - (R + B))\n17. value-mean:  3-d nonlinear transformation\n          of RGB. (Algorithm can be found in Foley and VanDam, Fundamentals\n          of Interactive Computer Graphics)\n18. saturatoin-mean:  (see 17)\n19. hue-mean:  (see 17)\n",
